Resumen

La pudrición es el factor que mayor impacto tiene en la vida en servicio de los elementos estructurales de madera. En la mayoría de los casos, la pudrición se asocia con una acumulación excesiva de humedad en la madera. Las condiciones de diseño estructural tienen un efecto sobre el contenido de humedad y esto afecta la vida útil del material. Para realizar el estudio se hizo uso de un dispositivo experimental diseñado específicamente para incorporar diferentes condiciones de diseño estructural, evaluándose la evolución del contenido de humedad durante un período de tres años en Madrid (España) en diferentes posiciones afectadas por las condiciones de diseño. Se evalúa el efecto de la protección por aleros, la separación del suelo y la disposición vertical u horizontal de los elementos de madera sobre la evolución mensual del contenido de humedad y el riesgo de pudrición.
